Description

Here you find the raw data files and processing Mathetica scripts for data averaging and plots presented in "Observing the universal screening of a Kondo impurity" Piquard, et.al. Nature Communications 2023 :

The mathematica files "DataAveraging_[T]mK.wl" are used to average the raw data stored as "123CK_AllConfigs....dat", "1CK_AllConfigs....dat", or "1CK_MainRun....dat" with the corresponding temperature, and produce the "_OneFile_1CK_[T].dat" averaged data files.

The mathematica file "DataAnalysis.wl" gathers the "_OneFile....dat" files and analysis the data to finally export the data used in the plots, stored with a name "Export_....dat" .

The correspondance between the ".dat" files and the data plotted in the main figures (from Fig2 to fig 5) is given in the Export section of the "DataAnalysis.wl" mathematica file  : 

    Fig2 : "OneFile_1CK[T]_TauDet.dat", "OneFile_1CK[T]_eStep.dat"

    Fig3 :  "Export_XsiLinearFit.dat", "Export_tau.dat"

    Fig4 :  a)  "Export_XsiLinearFit.dat", b) "Export_TsTk_TXsiLinearFit.dat", "Export_tau.dat", "Export_kBTk1sEC8ToPlot.dat", c) "Export_TXsi_d(TXsi).dat"

    Fig5 : a) "Export_Mag9mK.dat", "Export_SortedMag9mK.dat", "Export_IncertitudeMag9mK.dat", "Export_Mag15mK.dat", "Export_SortedMag15mK.dat", b) "Export_MTExp238.dat", "Export_MTExp476.dat", "Export_MTExp2380.dat"

    FigS1 : "Export_X(tau).dat"

 

 

Those data are also given in the "Source data.xlsx" excel file, along with the data of the Figures 6 to 9.
